JOHANNES ADOLFBERGMANN, OF TORONTO, ONTARIO, CANADA.

ILLUMINATEI) SIGN.

To all whom it may concern Be it known that I, JOI-IANNES Anonr BERGMANN, of the city of Toronto, in the county of York, in the Province of On tario, Canada, have invented certain new and useful Improvements in Illuminated Signs, of which the following is the specification.

My invention relates to improvements in illuminated signs and the object of the in vention is to devise an illuminated sign which can be operated at a smaller cost than those at present on the market and which will, at the same time, be more effective in drawing attention thereto.

My invention consists of a cylindrical casing having a dished portion formed on each end thereof bearing the advertisement, a lamp suitably suspended in front of each dished portion, a rotating drum of transparent material surrounding each lamp, and suitable driving gear for rotating the drum all as hereinafter more particularly described and illustrated in the accompanying drawing in which Figure 1, represents a front View of the sign showing the dished portion and the lamp in front thereof. Fig. 2, is a side view of the sign. Fig. 3 is a vertical cross-section thereof. Fig. 4, is a vertical section through the rotating drum. Fig. 5, is a front view of the sign showing a modified form of lamp and driving gear. Fig. 6, is a side view thereof partly in section.

Like letters of reference indicate corresponding parts in each figure.

1 is the cylindrical casing being provided at its ends with the enlarged dished portions 2.

3 are the words of the advertisement extending around the same, each letter of the advertisement being preferably built up of a series of small mirrors 3*.

i are central disk-shaped members suitably secured to the portions 2.

5 are lamps, preferably incandescent electric lamps, mounted on the hollow brackets 6, each lamp being in front of the dished portions 2.

7 is the rotatable drum surrounding the lamp and having top and bottom plates 8 and S with central apertures designed to fit around the top brackets 6 and the lower brackets 9 respectively, said drum being capable of being rotated around the brack ets 6 and 9.

Specification of Letters Patent.

Application filed December 8, 1911.

Patented Mar. 3, 1914. Serial No. 664,579.

10 are reflectors secured to the lower brackets 9 for throwing the light onto the letters.

The drum 7 is composed of a number of small glass plates of varied colors. The brackets 6 and 9 are secured to the central disk members 4. The wires 11 for the lamp,

where an electric lamp is used, are passed down the upper bracket 6 and a suitable socket 12 is provided at the lower end of the bracket.

13 are sleeves secured to the upper plates 8 and provided with suitable friction wheels l t at their upper ends.

15 is a cross shaft mounted on a suitable bracket 16 and driven through a belt 17 and pulleys 18 and 19 from a motor 20.

21 are friction wheels at each end of the shaft 15 engaging friction wheels 22 on the inner ends of inclined shafts 23, the outer ends of the inclined shafts .23 being provided with friction wheels 2 f engaging the aforesaid friction wheels 14.

32 is an opening formed in the casing and covered by thehood 34..

In the modification shown in Figs. 5 and 6 the lamps are disposed horizontally and are supported by horizontal brackets 35 extending through the central members 4. 36 are drums of truncated conical form having reflectors 37 at their outer ends, the inner ends being provided with sleeves 38 surrounding the brackets 35 and being capable of being rotated thereon. 39 are friction wheels secured to the said sleeves, and meshing with beveled friction wheels 40 on the ends of the cross shaft. The remainder of the driving mechanism is identical to that already described.

l/Vhen the lamps are rotated the light is thrown on the mirrors forming the words of the advertisement.

Many modifications may be made in the invention without departing from the spirit of the same or the scope of the claims. For instance, I do not wish to confine myself to the present form of driving gear for the drum as any suitable driving means will do equally as well.

lVhat I claim as my invention is:

1. An illuminated sign comprising a series of mirrors forming each letter of the advertisement, dished members inclined inwardly from the vertical toward each other for holding the mirrors, a casing joining the members together, a lamp in front of each 'central disk members, hollow downwardly 2. An illuminated sign comprising aseries of mirrors forming each letter of the'adveitei 'tisement, d1shed members inclined inwardly from the vertical toward each other for holding the mirrors, a casing joining the members, a lamp, in front of each member,

turned brackets secured to the disk members from which the lamps are suspended, barrelshaped drums formed of sections of glass of different colors "surrounding the lamps and having top and bottom plates with central apertures therein sleeves secured to the top plate of the drum, lowerupwardly turned brackets, the drums mounted freely 0n thelower brackets and the sleeves surrounding the upper brackets, reflectors behind the drums, friction Wheels secured to Hthe sleeves, a cross shaft having a pulley keyed thereto, a motor having a pulley on the shaft thereof driving the cross shaft through a belt extending over the aforesaid pulleys, friction wheels on the ends of the cross shaft inclined shafts, friction wheels on the inner ends thereof engaging the frictionkvheels on the cross shaft and friction wheels on the outer ends of the inclined shafts engaging the friction wheels on the sleeves of thedrum as and for the'purpose specified.
